Notes:
Performance is in Internal Throughput Rate (ITR) ratio based on measurements and projections using standard IBM benchmarks in a controlled environment. The actual throughput that any user will experience will vary depending upon considerations such as the amount of multiprogramming in the user's job stream, the I/O configuration, the storage configuration, and the workload processed. Therefore, no assurance can be given that an individual user will achieve throughput improvements equivalent to the performance ratios stated here.
IBM hardware products are manufactured from new parts, or new and serviceable used parts. Regardless, our warranty terms apply.
All customer examples cited or described in this presentation are presented as illustrations of the manner in which some customers have used IBM products and the results they may have achieved. Actual environmental costs and performance characteristics will vary depending on individual customer configurations and conditions.

SHARE Helps Out! There were 800+ MVSE requirements… We asked for SHARE’s help in focusing the effort SHARE came through! Special thanks to these people for boiling down the ocean:
Brad Carson, Tom Conley, Ed Jaffe, Robert Jenkins, Sam Knutson, Mary Anne Matyaz, Cheryl Watson, Dave Whitney (IBM)
(Apologies to anyone I’ve missed!)
Original intent was the “MVSE Top 40”
…perhaps with apologies to Casey Kasem… …but there was a large n-way tie for #40… …So, we got the “Top 39”
Due to timing, one was already satisfied in z/OS V1.13
PARM('AGGRGROW') Should be Default for zFS Mount (Hey, we like the easy ones!) Top 39er!
In addition, we think we hit another twelve or so in z/OS V2.1:
1. Dynamic system symbol changes2. Separate wait time limits (partial)3. Dynamically add and delete MCS consoles4. Consoles support for HMC 3270 emulator5. D PPT command6. Improve IEF212I message7. Dynamically modify VLF8. SETSMF without PROMPT at IPL time9. IEBCOPY partially-qualfied member names10.Multiple ISPF logical screens for SMP/E11.TSO Logon Failure information (partial?)12.REXX: Should Support Major Access Methods (partial)
As “No good deed goes unpunished*” …now it’s time to focus on the new Top 50!

• “Thin” interrupts for CFs• CFCC polled for work to do, so all CF engines were 100% used• So, shared engine CFs had a very limited use case
• A CF always used its entire PR/SM™ timeslice except in DYNDISP=YES mode• Not a great way to implement many/most production CFs
• New CFCC design in CFLEVEL 19 on zEC12 and zBC12 servers along with XES/XCF changes designed to use a more interrupt-driven, hyrbrid approach
• Should allow the use of shared engine coupling facilities in many production environments with acceptable performance
• Intended to lower Parallel Sysplex entry costs by reducing the number of environments for which dedicated coupling facility (CF) engines are needed to achieve good performance
• Also, new set of “thin” interrupts to be used by z/OS• Designed to decrease response time on the average• Help reduce XCF and XES processing overhead and improve performance
when processing asynchronous coupling facility operations and recognizing certain CF events

Three Ways to Compress (and Decompress) on z/OS Software compression
CPU-intensiveMuch slowerData can be inflated on anything supporting the same algorithm
Compression coprocessor-based instructionsDictionary-based compression, generic or tailoredCan be inflated on a System z processorAll compression consumes apparent CP cycles
• Compression done on the coprocessor, but accounted for as CP busy time because the CP is unavailable until the coprocessor is done
New zEDC Express adapter for zEC12 and zBC12 and zEnterprise Data Compression (zEDC) for z/OS V2.1Compression work is offloaded to the cardMinimal CP cycles consumedzlib-based, industry-standard deflate compressionData can be inflated anywhere zlib processing is available
SMF Data Compression For SMF data written to log streams
We expect about a 4:1 compression ratio for SMF dataDesigned to significantly increase SMF recording ratesCan specify that all SMF data or SMF data written to selected
log streams be compressedNew SMFPRMxx COMPRESS keyword on LSNAME and

IBM zEC12 and zBC12 System Functions and Features
* Statements regarding IBM future direction and intent are subject to change or withdrawal, and represent goals and objectives only.
But internal testing shows us ~4X compression for SMF data
Last SHARE, I said I expected (at least) ~2X compression for Extended Format BSAM/QSAM data, but we had not tested yet
Test numbers are in!
For BSAM/QSAM we see up to 4X compression for zEDC
• That’s as much as 2X better than generic or tailored compression
Also, for BSAM/QSAM we see 80% or more CPU time reduction compared to tailored and generic compression
• CPU cost for zEDC is ~0.1sec/GB in testing on a zEC12
* Based on projections and/or measurements completed in a controlled environment. Results may vary by customer based on individual workload, configuration and software levels.
(Note: LZ compression is used in the tape controllers already)

Migrating to z/OS 2.1: Parts 1 & 2Monday 3:00 & 4:30
• Generally speaking, z/OS Version 2 is designed to provide the same support of standards as z/OS Version 1
• These include the applicable standards or parts thereof…• FIPS• EMVCo and PCI• Common Criteria• RFCs• IPv6 Phase 2 Ready and USGv6 Profile Version 1.0 (NIST SP500-267)• Unicode• De facto industry standards• etc.
• …for the functions in z/OS Version 2 existed in z/OS Version 1
A Word About Standards*…with designs intended to provide:
* Statements regarding IBM future direction and intent are subject to change or withdrawal, and represent goals and objectives only.
• First MVS™ system integrity statement issued in 1973—about 40 years ago!
• It defined “System Integrity”• It applied to specific products, most of which are now part of z/OS• It said we would accept APARs for system integrity exposures
• Programming standards have been in place for decades for prevention
• System integrity competency center reviews code, helps resolve issues
• Reaffirmed periodically in various announcements for MVS, OS/390®, and z/OS
• In the z/OS 1.9 availability announcement, IBM expanded the scope of system integrity to encompass the entire z/OS product
• Once in a while, we have forgotten to reaffirm our commitment to system integrity on a version boundary…
• …and a number of people asked about it as a result.
• With z/OS Version 2, IBM remains committed to z/OS system integrity.
• System integrity is defined for z/OS as the inability of any program not authorized by a mechanism under the installation's control to:
• Circumvent or disable store or fetch protection; or,• Access a resource protected by the z/OS Security Server (RACF®); or, • Obtain control in an authorized state; that is, in supervisor state, with a
protection key less than eight (8), or Authorized Program Facility (APF) authorized.
• In the event that an IBM System Integrity problem is reported, IBM will always take action to resolve it.
• z/OSMF V2.1 uses WAS with the Liberty profile• Designed to simplify z/OSMF setup & cut memory footprint• Expected to start more quickly and use less CPU
